1993 Ranger will not start with Key

[93rangerxlt]

Ok first off I am new to this forum, but not to forums at all.
I just bought a 1993 Ford Ranger 4.0L Extended cab and I knew when I bought it that it ran because just in Febuary I replaced the clutch in it.
I got it home and the owner told me how he got it running. He would take a set of jumper cables and hook them to a car and then hook the negative to the negative battery and then to the starter relay (which is not good for the starter). So I replaced the ignition switch which did not fix the problem, replaced the starter that he burned up running it the way he was.
The starter relay is brand new also.
Now I am stumped no power to anything with a good battery and turn the key and nothing happens. The wires to the starter are all good and the wires from the relay are all good. I checked everysingle fuse in the fuse boxes and none are blown so I have no clue and any helped would be appriciated greatly.
I am sure I have left something out so any questions please ask.

Get a wiring diagram and make an enlarged copy. Use a meter or a test light trace where the power failure is. Check the plugs and connectors behind the fuse panels to make sure the connections are good.

did you put a test light on the small post of the solenoid when the key was in the start position?

very possible it is the neutral start switch sam

This is a standard transmission and should have a switch for the clutch pedal.
With an ohm meter across the contacts it should go from zero to 1 as somebody presses the pedal.

Question: Does this truck have a anti-theft?

Maybe replacing the tumbler the anti-theft cannot detect the key or the switch for that matter.

sounds like what happened on my 92. replace the battery cable ends at the battery,on mine the connection was bad inside the factory crimped cable end.hope this helps
